Be it known" that I,'MAURIOE GANbY, of

part of the United Kingdom of Great Britain an improved belt orband for driving machincry and an improved mechanical process of ing is a description'in such full, clear, and exact terms as to enable any one skilled in the arts or science to which it appertains to makeand, ,use the same, reference being bad to the accompanying drawings, making a part of his specification, by which there is illustrated certain machinery used in" the practice of my in vention, and in which- Figurel is a cross-section of the sewing-machine referred to as used in my improved process. Fig. 2 is a front elevation oflthe rollers shown at Fig. 1. Fig. 3 is a front elevation of a part of the sewinganachine. I Fig. 4 is a referred to as used in my improved process. Fig. 5 is a front elevation of the same; Fig. (i, a detached part thereof and Fig. 7, an adjunct, t he use and relation of which will be My'invention consists, first, of an improved cotton belt; second, of an improved mechanical process of m akin g a cotton belt.

The belt consists, first, of cotton canvas or duck composed of warp stonter than the weft, both warp and ,weft being hardspun and the canvas hard and tight woven; second,-of cotton canvas or duck thus made folded and united by longitudinal rows of stitching and stitched under tension third, of cotton canvas thus made, foldedyand' stitched, saturated with linseed-oil; fourtlnof cotton canvas thus made, folded, stitched, and saturated with lin seed-oil, pressed and stretched until it is hard, even, and rigid, by which the belt is rendered The method or mechanical process of makvas upon the line of its warp, either in a machine or by hand, to the thickness desired; second, of stitching it by a suitable machine upon the line of its warp with as many rows of stitching as may be necessary to thoroughly forced hard upon each-other; ibnrtlnot'stretcliing the belt in the operation of pressing it until its lEQnSilB elasticity is practically exhausted and the liability of the belt to st etch in use is removed.

In the drawings, Fig. 1 represents a side'elevatiou of a portion of a sewing-machiuc, nippers, and feeding-rollers, by which the belt B is sewed while under tensionf Z are the driving-pulleysof' the sewing-machine. (See also Fig. 3.) 'Yis' a disk with aearn-grcove, which operates, by Ineansof the bell-crank lever V, the springrpawl lever WV, and thereby feeding and pressing rollers X; Theieeding and pressing rollers X intermittently pull the belt B through and from the nippers U, which hold the belt, and the needle Q of the sewing-inachine sews the belt while under strain. The feeding-rollers X are driven by a pulley, and

are brought into operation by the machinistpended in the oil substantially in the mannershown.

The belt, after being sufficiently soaked with Y the oil, is led up between a pair of rollers, S S, by which the free oil is stripped off it, and thence forward between a pair of friction-r011 ers, R, and two pairs of nippers, B B, passing on its way between the calender-rollers (J G and (3 as illustrated. o

.Each of the nippers is provided with an adjusting-screw, E, by which the nippers are forced upon the belt and its tension-under the rollers is regulated. There are nippers on each side of the rollers; but those on the delivery sidearc left open when in operation to allow the belt an unobstructed passage between them. A The rollersare arranged to rotate alternately in oppositedirect-ions, by which the belt can be pressed and stretched first one way and then the other, firstfrom and then back to the oil-tank, until the oil is thoroughly soaked and forced into the fabric and every thread in the structure is drawn and pressed to its bearing, the tendency of the belt to stretch being thus d veloped to its maximum and its surface being brought to a hard anu equal plane.

The two lower calender-rollers, G C, have their axis supported by stationary bearin gs in the frame A; but the roller 0 is carried by ab adjustable frame, which, through the agency of the jointed rod Q and the-lever I, is forced down by a weight, W, upon the bottom rollers, as shown by Fig. 4, I

By Fig. 6 is shown a top view of the nip; pers and a section through the frame by which they are supported.

It is not intended to confine the patent ofwhich-this is to be the specification. to the especial form of machines, apparatus, or mechanical appliances-above described, the invention being not of any machine especialls', but of the belt and of the mechanical process 'by which it is produced,

stretched; then saturating it with oil to mal e it proof against dampness; then drawing it through stretohers and between rollers, to

stretch the belt and force the fabric full of oil and make the belt hard, rigid, and smooth.

12. Theim proved article of manufacture consisting of a hard, even-surfaced, rigid, impervious, non-elastic belt composed of cotton can'- vas 0r duck having its warp-thread larger than the weft, both warp and weft beingv hard-spun, the fabric tight-woven and folded, stitched, and saturated'with linseed-oil.
